– Wide application range due to
– availability in four viscosity grades
– compatibility with a wide range of plastics and elastomer materials




BARRIERTA is Europe’s oldest high-quality brand of hightemperature lubricants based on perfluorinated polyether oil (PFPE). The name of BARRIERTA is widely regarded as synonymous with long-term stability and thermal resistance. BARRIERTA products are among the most widely used PFPE lubricants today.

BARRIERTA Fluids are based on highly refined PFPE oils. Thanks to their excellent thermal stability and availability in four different viscosity grades, BARRIERTA Fluids have proven successful for many years in a large variety of applications.

BARRIERTA I SFLUID is NSF H1 registered and therefore comply with FDA 21 CFR § 178.3570. The lubricants were developed for incidental contact with products and packaging materials in the food-processing, cosmetics, pharmaceutical or animal feed industries. The use of BARRIERTA I SFLUID can contribute to increase reliability of your production processes. We nevertheless recommend conducting an additional risk analysis, e.g. HACCP.



Bearings and guides


BARRIERTA Fluids attain long service lives in rolling bearings, plain bearings, sintered metal bearings and guides subject to extreme temperatures or aggressive chemicals.
Owing to their low vapour pressures, and depending on the viscosity grade, BARRIERTA Fluids are also suitable for highvacuum applications.


Electrical contacts


BARRIERTA Fluids offer long-term protection against wear on electrical contacts, especially those with gold surfaces. There are no known decomposition products that would have an insulating effect on the contacts.




BARRIERTA I S Fluid is suitable for the lubrication of high temperature chains and even meets stringent hygiene requirements. BARRIERTA IS Fluid is non-toxic and nonodorous.


Plastic-plastic friction points


BARRIERTA Fluids are generally regarded as neutral towards elastomers and plastics (possible exception: perfluorinated rubber). A negative impact on materials is not to be expected. Nevertheless, we recommend testing the lubricant’s compatibility with the materials in question prior to series application.

Application notes


We recommend cleaning all parts to operate in contact with the lubricant with white spirit 180/210 and/or Klüberalfa XZ 3-1. Upon cleaning, apply clean compressed air or hot air to remove any residues. The friction point should be clean and bright (i.e. free from oil, grease or perspiration) and free from contamination particles to ensure optimum function.
